The procedure for receiving data sequentially, using the wait states (WAIT bit) for
synchronization with ICDR (ICDRR) read operations, is described below.
The procedure below describes the operation for receiving multiple bytes. Note that some of the
steps are omitted when receiving only 1 byte. Refer to figure 16.11 for details.
